Zuzana is waiting in a bar for her boyfriend, Tomáš Ulrych, and accidentally meets a nice young man, Mark Borský. The young man invites her for a drink. When he sleepily escorts her to her car, he tries to pull her into a dark passage, but Zuzana resists. The next day, a young girl Zuzana's age is found dead in a dark courtyard. They discover that the victim was sexually abused, but with no sign of a struggle. The only trace of the killer is a cufflink, and Susan sees the same on Mark's shirt.
